.new and useful Improvements in Door Holders and Latches, of which the following is a specification.

This invention relates to a combined doorstep holder and door latch particularly adapted to be used in connection with garage doors, although not restricted to such use.

An important object of the invention is to provide an improved device of the character mentioned for retaining the door in an open position, and for also latching the door. in closed position, in combination with operating means for so actuating the device as to release the locking device and thus permit the door to be readily moved from its open position to its closed position and vice versa. I

Other objects and certain advantages of the invention will become apparent from the following description when taken in connection with the accompanying drawings in which Figure 1 is a view in elevation showing the device applied to a door and so positioned as to lock the door in closed position.

Figure 9 is a detail view showing, in elevation a bolt structure, as attached to the bottom of the door and adapted to cooperatewith the door holder.

Figure 10 is a fraginental plan view of a door, having the bolt structure, shown in Figure 9, associated therewith.

In the drawings, wherein for the purpose of illustration is shown what I at present consider the preferred form of my invention, the numeral 5 indicates a door facing or frame to which a door 6 is adapted to be connected, as by means of hinges 7. The device for locking the door in its closed position, as shown in Figure 1, and for retaining or holding the door in its open position, as shown in Figure 2, comprises an elongated tube or locking element 9, one end of which is provided with a lip 10 adapted for pivotal connection to a bracket 11 suitably connected to the door, as by means of screws 12. This tube is cut away at the other end, as shown, thus providing a notch 13 and forming a pair of depending cars 14-. lVithin the tube 9 there is arranged an elongated rod or shaft 15, one end of which is bent to provide a lever 16, and the other s end of which is journaled in a downwardly bent lip 17 at the end of the tube. The journaled end of the rod is bent over upon itself, thereby forming a lifting linger or cam 18 which extends along the outside of the tube for an appreciable distance and is, at its end, bent in towards the tube to provide a cam finger'19 which insures unob structive movement of the notched end of the tube from .its locking position shown in Figure @1- touits holding position shown in F i 'ure 5 as will hereinafter more clearly appear.

To the door facing 5, there is connected bracket 20, the depending arm 21 of which functions as a suitable stop for the free end of the rod 9 whenbeing moved from its position shown in Figure 2 to its position shown in Figure 1. A catch having a base 22 is suitably connected to the door 6 and is provided with an angular projecting portion 23 having a notch 24 formed therein and provided atits outer end with a bevel or inclined face 25 over which the free end of the tube 9 is adapted to slide as the door approaches its closedposition To the frame 5, relatively near the pivoted end of the tube 9, whenthe door is in its closed position, there is suitably connected L t'i a guide or supporting element 26 through which the tube is adapted to slide'when the door being moved from one position to the other. This guide functions as a means adapted to cooperate with the notched end of the tuhe 9 to hold the door in its open position. In moving the door from its closed position to its open position. the tube 9 tree to slide or move through the guide until the door has assumed its outermost Figures 3 and 'lfhen re notch 13. after the linger 18 has been irec'ted into the guide it; hv the cam 19. illows the tree end of the tuhc 9 to so drop to permit the guide 26 to enter the notch As the tuhe S) drops to its holding posilion l est shown in figure 5. the linger 18. due to the weight of the tuhe 9. is lifted to the position shovn in Figure 5. in which p o ten it remains until it is so rotated, with respect to the tuhe 9. 15 to lift. or elevate the. tree end thereot and thus free the guide 26 from the notch to allow the door to he moved from its open position to its closed position. In order to rotate the shaft 15, with respect to the tube 9. a suitable chain 27 mav he employed. which chain is connected to the outer end ot the arm 14}. After rotatingthe shaft or rod 15 and thereby so lifting the free end of the tuhe 9 as to disengage the guide 26 from the notch 13. the door (3 ma he moved from its open position to its closed position. and as a result of this movement the tube 9 is permitted to treelv slide through the guide 26. Its the door approaches its closed position. the free end of the tuhe moved to vards the bracket it). meeting; the heveled end 25 of the catch and sliding over the same into the locking position shown in Figure (3. just as the door readies its closed position. lfpon completion of the late al movement of the tuhe 9. the free end thereof drops under its own I so that the catch enters the notch 1 and the. arm 18 rests upon the top of the e-' ensior Qt of the catch, while the notched tree end of the tuhe is positioned in the notch 24- of the catch. with the tree end of the tube positioned as inure weight.

t... shown in 1* (i. it is apparent that the door 6 is iOCl -IOd aouinst opening. inasmuch as the extension Qt. cannot move tor the reason that the tuhe 9 is held intermediate the dep .ndinp; arm of the l)t'1('l 0i' 20 and the extension it of the catch. To release the locking engagement ot the tuhe 9 with the catch. the shatt .5 ma: he rotated. with respect to the tuhe h menus of the chain 727 to etl eet relative movement het-ween the linger 1S and the tu e wherehv the linger l d. due to its engagement with the extension of the catch lil'ts the free end of the tuhg 9 to the position shown in Figure 7. ther h v permitting; the free end ot the tale unohstructed over the top of the extension Eel-of the etch and at cnsion the same time permitting l: the do is l n to pass through the notch 1 a opened.

An auxiliary locking device in the form of a holt. indi ated as a whole in Figure l hv the numeral 29. mrv he provided. This holt comprises a suitable guide i which is secured to the door (3 and carries a reciproeating locking element ill. mounted in the later-all extending flanges 32 ot the hraclict and adapted to engage a hex-per 13 which mav he Fa'nrcd. h any suitahle means to the threshold ot the door. The locking." ment 31 is provided with a volte i-l adapte tor the reception or" a cranl; arm

t carritul a one end of an operating shalt li which. at its other end. is journaled in suitahle hracltets ST and 3S and provided with an arm ll) adapted to he connected to the chain 27. The locking element I). may lie relrasc'l trom. the keeper 33 through the hal'i and chain connections sinmltaneouslvwith tlurel-ase of the notched end of the t tho 5) from the, catch extension 2 living thus descrihed mv invention.
